Visitors will be greeted at all three of the entrances to the park by volunteers and docents from the Petaluma Wetlands Alliance, volunteer caretakers of the park year-round.

Participants are encouraged to wear red, in order to be visible from the air when a spectacular aerial photograph is taken at 3 pm.

With enough people, organizers hope to ring Shollenberger Marsh, the most sensitive portion of the park, where the harvest mouse lives!

A berm has been specially mowed for this purpose. Designated bicyclists will be on hand as 'border collies' to keep people on paths. Volunteers will be wearing safety vests in order to be easily identified.

Depending on ambulatory speed, it is suggested that participants begin around 1:30 pm. A bike brigade will leave Aqus Café at Foundry Wharf at 12:30, where a free regular cup of coffee, post-event, will be offered to anyone who has attended this special event.

Final staging will occur at the park at 2:45, and the photo will be taken at 3:00 pm.
